I quickly checked the SoundManager code, and it appears the "PlaySound" function calls through to FMODs "playSound" function. In FMOD "playSound" is not a blocking operation, it will start playing the sound in another thread, then return. So since you are deleting the sound manager right away, it hasn't had a chance to play anything yet.
I believe the SoundManager needs to get updated and this is done by frameStarted(). This means for your sound to start playing you have to start running your Ogre application using root->startRendering();. Have you tried that? The above code is either incomplete (in which case you really do have a problem) or you just have to get the update of the SoundManager started off by starting the graphics to render and thus call frameStarted of SoundManager.

我快速检查了 SoundManager 代码，发现“PlaySound”函数调用了 FMOD 的“playSound”函数。在FMOD中“playSound”不是一个阻塞操作，它将在另一个线程中开始播放声音，然后返回。因此，由于您立即删除声音管理器，因此它还没有机会播放任何内容。

我相信 SoundManager 需要更新，这是由
frameStarted()完成的。这意味着要开始播放声音，您必须使用root->startRendering();开始运行 Ogre 应用程序。你尝试过吗？上面的代码要么不完整（在这种情况下你确实有问题），要么你只需要通过启动图形渲染来启动 SoundManager 的更新，从而调用 SoundManager 的frameStarted。I believe the SoundManager needs to get updated and this is done by
